Towards a unified terroir zoning methodology in viticulture

Abstract

In viticulture, terroir is a key concept that refers to an area and thus possesses a geographical dimension. Hence, zoning of viticultural terroir is an important issue. This paper addresses soil and climate related aspects of terroir zoning. The first step of the zoning process is a clear identification of the objectives that are being pursued. Soil zoning and climate zoning methods are presented separately, although both approaches are preferably carried out simultaneously, in order to take into account soil-climate interactions in the terroir effect. Definition of a scale adapted to the objectives is critical, particularly so in soil zoning. For soil zoning, the relevance of geology, geomorphology and pedology (soil science) is discussed. The use of new technologies (e.g. GIS or remote sensing) enables the production of more detailed maps at reduced costs. In climate zoning, climate data and agroclimatic indices must be chosen according to the zoning objectives. High quality climatic data must be selected and validated. Following, homogeneous climatic zones are indentified. Viticultural zoning has to be validated, preferably so by eco-physiological studies. This paper is based on the unified terroir zoning methodology that is currently in preparation by the experts of the International Organisation of Vine and Wine (OIV).

CHARACTERIZATION OF ENOLOGICAL OAK TANNIN EXTRACTS BY MULTI-ANALYTICAL METHODS APPROACH

Oak tannin extracts are commonly used to improve wine properties. The main polyphenols found in oak wood extracts are ellagitannins¹ that release ellagic acid upon hydrolysis and comprise numerous structures². Moreover, oak tannin extracts contain other compounds giving a complex mixture. Consequently, the official OIV method based on gravimetric analysis of the tannin fraction adsorbed on polyvinylpolypyrrolidone is not sufficient to describe their composition and highlight their chemical diversity.

Vino e paesaggio: materiali per il governo del territorio vitivinicolo. Il piano regolatore delle città del vino

S’intende per Piano Regolatore delle Città del Vino la metodologia per redigere la parte strutturale dello strumento comunale di governo del territorio. Parliamo, infatti, del principale strumento comunale di governo del territorio, così come è venuto maturando nella riflessione delle Città del Vino, strumento che si misura con la sfida di governare tutto il territorio in modo coerente e sostenibile, a partire dal riconoscimento del valore del “sistema vigneto” e della sua intrinseca fragilità.

Sur la réalité du lien entre le terroir et le produit : de l’analyse sémantique à l’approche écologique

The reflections presented here are a synthesis of a set of research on the construction of a scientific logic concerning the relations between the terroir, the vine, the wine, and on the study of a product, the wine, considered as the resulting from many interactions between factors of various orders. This work has benefited greatly from discussions of an epistemological as well as a technical nature with all the researchers at URVV (Angers) and with our colleagues at the Institut National des Appellations d’Origine, over several years.

Metabolic fingerprinting and qualitative attributes of two indigenous Cypriot cultivars destined for the production of ‘commandaria’: the impact of leaf removal and dehydration process

Grapes’ sun-drying is one of the most critical steps in the production of ‘Commandaria’, a dessert wine with Protected Designation of Origin that is exclusively produced in Cyprus from grapes of the two indigenous cultivars (Vitis vinifera L.), namely ‘Mavro’ and ‘Xynisteri’. Despite its significant economic importance, no data regarding the primary and secondary metabolites of the aforementioned cultivars exist.
